Which of the following is a reason for disaffirmance of a contract?

Disaffirmance of a contract generally refers to the right of a party to void or cancel a contract under specific circumstances. The age of majority is a key factor in this process. Individuals who have not yet reached the age of majority, typically defined as 18 years old in many jurisdictions, have the ability to disaffirm contracts they entered into while still a minor, which protects them from being bound by agreements they may not fully understand or may not be in their best interest. This legal protection acknowledges that minors often lack the maturity and experience necessary to make informed decisions regarding contractual obligations.

In contrast, mutual consent refers to both parties agreeing to the terms of the contract, which does not validate disaffirmance. A unilateral error pertains to a mistake made by one party and does not provide grounds for disaffirmance unless the other party had reason to know of the mistake. Implied authority deals with the capacity of someone to act on behalf of another, which doesn't specifically relate to the disaffirmance of contracts as influenced by a party's age. Understanding these distinctions is crucial for recognizing the rights and protections under contract law, especially as they pertain to minors.
